A stereotaxic apparatus for injection of the trigeminal root and ganglion.
A stereotaxic apparatus was designed which would enable a needle to be passed easily through the foramen ovale with accuracy and with a minimum of radiological aid by one relatively unskilled in injection of the trigeminal ganglion. Successful penetration of the foramen was achieved in 39 of 46 injections on cadavers and in six injections on five patients. The substance injected was 5% phenol in glycerin. In one patient alcohol was used. The anesthesia produced was satisfactory in all except one patient. We feel that this apparatus will enable the trigeminal ganglion to be injected relatively easily in all patients except those with unusually shaped skulls.
